Wow! Thanks for the info. He's currently taking 2 tests a week (just passed biology last week which put him at 45 credits) and is scheduled to take US History II on Tuesday which will put him at the magic number 48 you mention. Incidentally, his only study source has been InstantCert and he's racking up the credits so fast the folks at the recruiting station thought it had to be some kind of scam. Until you sent the link though, I didn't know there was any written guideline on rank and education as far as enlistment. I thought it was all up to the recruiter unless you had a degree. But thanks to your helpful post I'll print out the chart and when we go back to see the recruiter we'll take it with us. Knowledge is indeed power. By the way, we're hoping to have him finish at least 60 credits by the time he leaves for boot camp and submit it all to Charter Oak for an Associates degree. thanks again for the post!
